SEECRTEGAZIJNY forming part of Le ters Eatent No. 679,916, dated August6, 1901.

Application filed October 29, 1900. Serial No. 34.703. (N model) Z107mm, i1 may coitcswt;

lie it known that i, FRIDOl'iEiZ dcninnnn, a citizen of the UnitedStntcs, residing at Faribnnlt, in t? so nniy of Rice and State of Minenesoin, i ve invented certain new and useful improvements inBridge-Berni for Pianos; end I do hereby declare the following, to be afull, clear, and exact description of the inven tion, such w ll. enableothers skilled in the art to which it zippertnins to make end use thesome.

invention has for its object to provide an improved bridge-bearing forapplication between the strings and the sounding-board of s. pinnoforte.

To the above end the invention consists of the novel devices hereinafterdescribed, and defined in the claim.

Theinvention isillustrated in the accompanying drawings, wherein likechm-actors indientc like parts throughout the severalv views. "ure 1 e.plan view showing 11 portion oi no bridge-bar of the sonnding'bonrd andportions of n set of strings, together with one of my improvedbridge-bearings applied in working position. Fig. '13 is n vcrticnlsection on thclinew w oi. Fig. Ii. Fig. 53 is c. \ti'hlifitl Sectionthrough the bridge-bearing npproximately on the line 11.1 of Fig. .l,and Fig. l is a perspective view of the said bridge-beering removed fromworking position.

The numeral 1 indicates the bridge-liniof n sounding-board oi? epinnoforte, and the numeral 2 indie-(ties nset oi strings to wit, threestrings tuned in unison to produce a given note.

The bridgebeering consists base-pinto or portion 0., provided its on swith transverselyextended benringflanges o: egrnffes l) and stone sidewith e. lonezitndinnlly-extended web 1;, cast integral with said (L andflanges I). The control portion of the web 0 is curved upward, and fromthe intermedinte portion thereof on integrally-formed. and over- 45lying string-engaging log or ngrsrfc (Z projects pnrnllel with saidflanges Z),witl1 its under edge extending above the base a, but below aplane intersecting the upper surfaces of said flanges b.

The bridge-bearing is preferably secured on the bridge-bar l by means ofscrews 6, pnsscd through suitable perforations e in the base a andscrewed into the said bnr.

With a. bridge-homing of this construction the three strings may beplaced in working position by lateral n'iovcment, and as the threebearing-surfaces of the zigraffes b Z; (Z extend parallel the stringsmay be adjusted and set at any distance apart and in any positionrelative to the side plate 0.

It is very important that all of the strings be placed in workingposition on the bridgeb eariug by lateral movements, for the reason thatdrawing the strings th ough openings or passages tends to damage thestrings and, furthermore, is with diiiiculty accomplished under the mostfavorable circumstances and in the case of certain of the largerstrings,

which have looped ends, cannonbe accom-' plished.

The integrally-formed bridge-benringabovo described may be cast withoutthe use of 11. core, and hence is of very small cost.

What i olaim,nnd desire to secure by Letters Patent of the UnitedStates, is as follows:

A Midge-bearing comprising the base a with parallel end flanges oragrnffes b, and side web 0 having at its intermediate portion theoverlying bearing-lug or egraffe d that projects parallel to saidagraflfies 1), whereby the strings may be applied to said bridge-bearingby lateral. movements in a common direction, substantially as described.

in testimony whereof I nffix my signature in presence of two witnesses.
